| 1.Water pressure resistance can be measured by two different methods. One is the low hydraulic pressure test JIS L1092 A. The pressure gradient for this test is 600mm H2O/minute. |
| 2.The second method is called the " high hydraulic pressure test " JIS L1092 B. The pressure gradient for the test is 10,000mm H2O/minute. |
1.The specimen is clamped at the test head, covered with a wire mesh screen
to prevent the specimen from getting inflated and to achieve a more realistic
testing result. |
2.The test is over when the water has penetrated the test specimen at three positions. |
